Reaction Steps

A solution of 2-amino-N-[3-methoxy-4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-5-phenoxy-benzamide [Example D1] (25 mg, 0.055 mmol) in 1,2-dichloroethane (1 ml) was treated with triethylorthoformate (2 ml) and the mixture heated to 80° C. for 16 hours. The mixture was cooled, 1 drop of DBU added and the mixture evaporated. The residue was subjected to flash chromatography on silica gel eluting with (methanol-dichloromethane-aqueous ammonia) to give the title compound;
